Modifier Feature: Local Prism

Function

Local Prism extrudes a cross section shape into a Solid.  It either adds the extruded solid to the selected Solid or removes the extruded solid from the selected Solid creating a hole.

Call

Geometry > Modifier Feature > Local Prism

<Local Prism>

Cut

A new shape extruded from the local Prism Profile is cut from the original shape.
 

Fuse

A new shape extruded from the local Prism Profile is added to the original shape using the Boolean Fuse operation.
 

Select Base Face

Select a Base Face, which will become the basis of extruding a local Prism Profile.
 

Select Local Prism Profile

Select a local Prism Profile (Face, Wire, Edge).  Only one profile can be selected at a time.
 

Select Local Prism Direction

Select a Local Prism direction for an Extrude operation.

Select Extrusion Direction

Select a direction (Datum Axis, Datum Plane, Face, Edge) for extrusion directly
 2-Pt Vector

Select a direction of extrusion by a vector which is defined by two specified points. The coordinates of 2 points may be specified using Snap.
 Normal of Profile(s)

Extrude the selected profile in the normal direction of the profile provided that it can be defined. If a Line or a curved Surface is selected as Extrusion Profile, it can not be used here since its normal direction can not be defined.
 

Reverse Direction

Set the local Prism Direction to the Reverse direction.
 

Drafted

Extrude the local Prism Profile by gradually reducing the cross sectional area.

Angle

Specify the draft (slope of reduction) angle.
 

Extrude Length Definition

Height

Specify the Height (depth of extrusion) directly.
Until

Extrude the profile up to the selected Face.
From Until

Specify a starting Face and an ending Face for the Extrude operation in the From Face button and the Until Face button respectively.
Until Infinite

The Prism Profile is extruded to infinity.  It is only applicable for the Cut operation.
From Infinite

The Prism Profile is extruded from infinity.  It is only applicable for the Cut operation.
Thru all

The Prism Profile is extruded from negative infinity to positive infinity.  It is only applicable for the Cut operation.

Notes

When a Edge of Base Face overlaps a Edge of Local Prism Profile, it may need more time to make Local Prism Cut or it might not make normal Solid.

Therefore, Local Prism Profile should be made of enough size not overlapping Edge of Base Face so that the part of Solid is eliminated.
